From b8cee18cc75d7b9dbe6c6526dfae9ab49e84fa95 Mon Sep 17 00:00:00 2001 From: Christian Borntraeger <borntraeger@de.ibm.com> Date: Wed, 21 May 2008 13:37:16 +0200 Subject: KVM: s390: use yield instead of schedule to implement diag 0x44 diag 0x44 is the common way on s390 to yield the cpu to the hypervisor. It is called by the guest in cpu_relax and in the spinlock code to yield to other guest cpus. This semantic is similar to yield. Lets replace the call to schedule with yield to make sure that current is really yielding.
